Powershell + What other coding language do you know/recommend?

Looking for suggestions on a new coding language to partake in and am curious what the panel of experts here use. I was thinking about learning python as it is cross platform, or potentially GoLang, but i’m keen to here what you guys think is the most complimentary in the DevOps/Automation/SysAdmin life.

So tell me beautiful people, What do you use other than PoSh in your day to day lives?
